Subject: [PATCH 1/9] ARM: kprobes: make more tests conditional
Date: Tue, 9 Oct 2012 17:22:55 +0200 [thread overview]
Message-ID: <1349796183-30648-2-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1349796183-30648-1-git-send-email-arnd@arndb.de>
The mls instruction is not available in ARMv6K or below, so we
should make the test conditional on at least ARMv7. ldrexd/strexd
are available in ARMv6K or ARMv7, which we can test by checking
the CONFIG_CPU_32v6K symbol.
